Whats a good technique to spike your hair straight? (not super perfectly straight)?

Hello, I am a hairstylist. I suggest using hair concrete or hair glue. Bead Head makes products especially for short hair. I like the manipulator and the mastermind. Hard to Get texturing paste should work well too. Just go to there store and look at all of the Bed Head products and read what they do and see which one will be best for your hair.
